Logo for the LPVEx field campaign.
The Light Precipitation Evaluation Experiment (LPVEx) took place in the Gulf of Finland in September and October, 2010 and collected microphysical properties, associated remote sensing observations, and coordinated model simulations of high latitude precipitation systems to drive the evaluation and development of precipitation algorithms for current and future satellite platforms.

LPVEx consisted of coordinated aircraft flights within an extensive network of ground-based observations to measure light rain, which comprises a large fraction of precipitation at high latitudes. LPVEx was a collaborative effort between CloudSat, the GPM Ground Validation (GV) program, the Finnish Meteorological Institute (FMI), Environment Canada (EC), the United Kingdom National Environmental Research Council, Vaisala Inc., and the University of Helsinki (UH).
